To all whom it may concern: between the adjacent ends of the rolls (1,e,

Be it lr'nown that I, Onaanns S. ,Loon and radial bars In between whichthe rolls wool), a citizen of the United States, residare fitted andrevolve, as shown in Fi 2. 111g at 289 Market: street, Newark, countylhe casing'is formed with abody I and an of Essex, and State of NewJersey, have invented certain new and useful Improvements inRoller-Bearings with Combined Thrust and Bearing Rolls, fully describedand represented in the following specificaadjusting ring m screwed intothe body, each having a tapering seat 11, therein to. embrace the outersides of the rolls (1, e. A. notch o is shown in the edge of the body Zto receive the head p of a screw, which is inserted in the periphery ofthe ring parts are properly adjusted, thus holding, theparts Z ant m intheir adjusted relation. Such parts are shown in my application 0.485,969 filed March 26, 1909 for patent on self-contained rollerbearing, but the present invention differs from that in providing ameans in the groovec,.and the flanges f upon the rolls, to positivelyprevent any end movement of the rolls. As the tapering seats in thecasin engage the inclined surfaces of the rolls, t io casing is thusheld ositively from end movement, and thebcarmg operates effectively toresist end-thrust as well as lateral strains An end view ofone-half ofthe cage is shown in Fi 4:, and to adapt such a cage to flanged 1'01 sthe cage is formed with a ertures p between the bars k, and the en ofing a part of the same. This invention relates to a'spccial form ofroller bearings in which a hub is provided to secure upon the axle andformed with conical seats havingthcir bases adjoining and two sets oftapering rolls fitted to revolve upon such seat.

The present improvement consists in forming the center of the hub withan. annular groove and providing the contiguous ends of the two sets ofrolls with flanges adapted to run in such groove, and thus enabled toresist end-thrust positively in either direction.

The invention will be understood by'refcrence to the annexed drawing, inwhich Figure l is a view showing a longitudinal section of the casingand cage; Fig. 2 is an end view of the bearing with the nearer ring suchaperture nearest the flange j is formed of the casing removed; and Fig.3 1s a side with notches g at its opposite edges which elevation of thehub. Fig. 4 is a view illustrating an edge view of one of the sections.

a designates the axle upon which the hub is secured by any suitablemeans and provided with two conical seats I), 6, having form clearancefor the edges of the rollflangcs f. In addition to the notches the flanes 9' of the cage are provided as s own in ig. 2 with notches 1'extending outwardly from the edges of the notches 1 their bases adoining and separated by a and of suilicient height to clear the corneagroove 0. Two sets of tapering rollsd ande ends 9 of the rolls, as shownin Fig. 1,

are shown fitted to revolve upon the seats 7), b, with their larger endsin contact with one another. These larger ends are formed with flanges fwhich project into the groove 0 and with contiguous conical surfaces gso that these conical ends may contact with one another inside of thenotches g and r.

A divided cage with simple apertures for the rolls is shown in my aplication No. 4-8:"),969 filed March 20, 1909, for patent on which rollin contact with one another an self-contained roller bearing, and myclaims serve to hold the flanges f in contact with the herein aretherefore limited to a cage havopposite edges of the groove 0, thusresisting provision for clearance for the rolling any end movement ofthe rolls. The flanges f, while fitted to the opposite sides rolls andthe seats I), b, are tapered in the same proportion, so that the rolsrevolve on the conical seats without sliding friction, and the conicalsurfaces 9 opera to in a similar manner. A cage is shown to hold therolls in place upon the seats Z), Z), such cage of the rolls to "uidethem in their movement around the hu Having thus set forth the nature ofthe invention what is claimed herein is:

1. In a roller bearing, the combination, with a hub having a groove atthemiddlo having flanges h which it upon cylindrica of its length withroll-seats atop osite sldes seats 3 at the opposite ends of the hub, ofthe groove, of two sets o rols fitted to flanges which are fitted andjoined together the roll-seats with their ends in contact over m whentheother, and a casing having tapering seats fitted to the outer sidesof the rolls.

In a roller bearing, the combination, with a hub having opposed conicalseats with their bases adjoining and ,a groove formed between suchbases, of two sets of taperingrolls fitted to revolve upon the seats andhaving flanges upon their larger ends fitted into the said groove, theflanged ends of the rolls having conical surfaces to roll in contactwith one another, and a divided casing having tapering seats fitted tothe outer sides of the rolls and adjustable to' bear snugly upon saidrolls.

4-. In a roller bearing, the combination,

with a hub havlng opposed CODlCtll SBlt-S with their bases adjoining anda groove formed between such bases, of two sets of rolls fitted torevolve upon the seats and having flanges fitted into the said groove,the

contiguous ends of the rolls having conical surfaces to roll in contactwith one another, a cage with openings to receive and guide the rollsabout the hub, and a divided casing having tapering seats fitted to theouter sides of the rolls.

5. In a roller bearing, the combination,-

with a hub having opposed conical seats Z), 6, with grooves at themiddle, of two sets of rolls rotated with their contiguous ends incontact and flanges upon such contiguous ends fitted to such groove, anda cage fitted to rotate upon the hub and havin the apertures 77 fittedto the bodies of the ro Is to guide the same in their movement and thenotches 9 arranged to clear the flanges of the rolls.

6. In a roller bearing, the combination, with a hub having opposedconical seats b, I), with groove 0 at the middle, of two sets of rollsrotated with their contiguous ends in contact and flanges upon suchcontiguous ends fitted to such groove and a cage fitted to rotate uponthe hub and having the inner flange h and outer flange y joined by theinclined guide-bars 76 with aperturesp between the guide-bars fitted tothe sides of the rolls to guide the same, notches g at one end of suchapertures with adjacent notches r in the flange j to clear the flanges fof the rolls.

In testimony whereof I have hereunto set my hand in the presence oftwosubscribin g witnesses.
